IPC: F04B1/20
Filed: 2002-01-21
Abstract: <P>PROBLEM TO BE SOLVED: To secure adhesion of a sliding surface of a valve main body part of a rotary valve in a rotary fluid machinery and a rotor.  <P>SOLUTION: This rotary fluid machinery is provided with the rotary valve 61 for controlling intake/discharge of a working medium for working parts 49 and 57 constituted of axial piston cylinder groups. A steam supply pipe 77 arranged on an axis L of the rotor 27 and supplying steam to the rotary valve 61 is provided separately from the rotary valve main body 62. A sealing means 97 constituted of a gland packing is arranged between the steam supply pipe 77 and the rotary valve main body 62. Since the flexible sealing means 97 has a function for preventing moving of the steam supply pipe 77 in the axis L direction from being transmitted to the rotary valve 61, adhesion of the sliding surface 68 of the rotary valve 61 is secured to enable sure supply/ discharge of steam, minimizing leakage of steam from an outer periphery of the steam supply pipe 77 by the sealing means 97.  <P>COPYRIGHT: (C)2003,JPO
